ROTARY ENGIINE OR PUMP.

QPECIFIGATION forming' part of Letters Patent No. 717,244, datedDecember 30, 1902. Appiimionfiiedocioberis,1902. saisine. 127.151.(Nomad.)

To all whom it may concern.:

Beit known that I, WILLIAM A. MORGAN, a-

citizen of the United States, and aresident of Dublin, in the county ofWayne and State of Indiana,have invented certainnew and usefulImprovements in Rotary Engines or Pumps,

of which the following is a specification.

The object of the present invention, broadly speaking, is the provisionof a device of the class described which will` produce a constantunvarying pressure convertible into either rotary power or for pumpingwater or other fluids.

Another object is to provide arotary engine or pump composed of aminimum of mechanical parts consistent with the various op-l enabled tocontrol its operation so thatits work will be performed with certaintyand precision.

Another object is the provision of a rotary engine or pump composed ofinterdependent and cooperating parts so arranged as to produce constantand unvarying source of power.v

Other objects and advantages will appear from the following specicatlonand from the drawings forming a part thereof.

The invention consists in a rotary engine or pump embodying certainnovel and peculiar features and details of construction and rela-` tivedisposition of parts, as hereinafter par# ticularly set forth, and itfurther consists in the legitimate combinations of the features referredto with each .other and with other features not yet alluded to and innumerous other subordinate but important combinations and also incertain specific construcltions., all of which will be fully describedhereinafter.

I attain the above and other objects and other important and subordinatefeatures by the mechanism and arrangement of parts :illustrated in theaccompanying drawings,

forming a part of this specification, in which `like indices ofreference denote and refer to `like parts throughout the several views.

Referring now to the drawings, Figure 1 lshows the interior elevation ofone side of my invention and the parts and arrangements peculiar to thatside and also a section of the 'controlling-valve.

Fig. 2 is a cross-section of the above taken on the lin'e X X of Fig. 1.

Fig. 3 shows the interior elevation of the side opposite to that shownin Fig. l and the parts and the arrangements peculiar thereto and also asection of the opposite side of the controlling-valve. Fig. 4 is across-section of the above, taken on the line X Xof Fig. 3. Fig. 5 is anelevation or plan of the revoluble disk operating between the partsshown in Figs. l and 3, the mechanisms carried by said disk, and asection of the main shaft. Fig. 6 is a crosssection of the parts shownin Fig. 5,-

`taken on the line Y Y of said view. Fig. 7

is a'detail view of one of the heads, its shaft, and its operativebevel-pinion; and Fig. 8 is an end view of said bevel-pinion.

Referring now to the drawings, A, Fig. l, represents the right-handmember of the cylindrical casing, and B, Fig. 2, the left-hand member ofthe same. The interior of the casing is formed into spaces of differentWidths and elevations by means of the oppositely-disposed correspondingsurfaces, as follows: The faces of the chimes a, and b are adapted to bebrought together and to be secured by bolts to be inserted in the holesa and b' of the respective members A and B. Immediately adjoining thechimes are the faces l and 2, whichwill be some distance apart When thechimes a and b are contacted,

for the purposes hereinafter set forth. With- `in the faces l and 2 inthe respective members A and B are circular concave surfaces C and D,forming the cylinder of the engine or pump, whose inner edges terminateon the respective surfaces E and F, which latter are parallel with andon same elevation as the faces l and 2. Seated in the outer edges of thesurfaces E and F are the respective open packing-rings G and I-I, whichresiliently rise slightly above the surfaces E and F. The

IOO

channels in which said rings are seated are beveled from the inner edgesdownward and outward, as shown in Figs. 2 and 4, and the inner edges ofsaid rings are beveled to correspond thereto, by which arrangement it isapparent that as said rings expand their upper surfaces are raised abovethe surfaces E and F.

In the lower portions of the members A and B are the respectivetrapezoidal abutments 3 and 4, whose surfaces are on a level with the yrespective surfaces F., F, 1, and 2, and which entirely close or breakthe continuity of the respective concave surfaces C and D. In the edgesof the respective abutments 3 and 4 at right angles to the surfaces Cand D, their inner ends abutting the respective rings G and H, are thetwo pairs of resilient packing-bars g g and h h', as shown in Figs. 1and 3. Radiating from the abutment 4, their upper surfaces on a leveltherewith, extending centrally into the ends of the concave surface Dand parallel therewith, are the oppositelydisposed wings 5 and 6, (shownin Fig. 3,) the purpose of which will hereinafter appear. Into theconcave surfaces C and D, below the axial centers thereof, are theoppositely-disposed pairs of grooves or channels I I and J J in the faceC and K K and L L in the face D, whereby the pressure may pass aroundthe pistons when they are at these points.

7 represents a surface within the surface E. 8 represents a smalleropposite surface within the surface F, and 9 represents a surfacebetween the surfaces F and 8 of same diameter as the surface 7.Extending up from the surface 8, Fig. 3, are the two pairs of bevel-gearteeth M and N, which lie parallel with radial lines extending from thecenter to the periphery of the casing and whose outer ends are on a linewith the inner edge of the surface 9. Immediately opposite the teeth Mand N and for a slight distance on each side thereof the surface 9 isscalloped out, as represented by O and P, in order to allow the shanks2l and 22 to revolve therein.

Referring now especially to Figs. 5, 6, 7, and 8, the numeral 10represents a rotary disk of a thickness substantially equal to thedistance between the surfaces 1 and 2 when t-he chimes a and b arecontacted and of substantially the same diameter as said surfaces. 11represents the hub integral of the disk 10 and of a diametersubstantially double the distance between the center of the casing B andthe inner ends of the teeth M and N. Extending through and beyond thehub 11, to which it is permanently secured, is the main shaft or axle12, which is adapted to be journaled in the openings Q and R of therespective members A and B, and to extend beyond the casing at each endto either or both of the projecting outer ends of the axle 12 a pulley(not shown) maybe attached, by which power may be transmitted from or tothe engine or pump. The numerals 13 and 14 represent two oppositelydisposed openings through the disk 10 near its outer edge opposite tothe concave openings C and D, the inner edges of said openings beingconcave. 15 and 16 represent the two disks or pistons, with convexedges, adapted to fit the respective openings 13 and 14, in which theyare adapted to revolve. Shafts 17 and 18 (shown in dotted lines in Figs.5 and 6) extend in from opposite points in the center of the peripheryof the disk 10, through the center of the respective pistons 15 and 16,and the inner ends are seated in opposite sides of the hub 11. 19 and 20represent bevel gear-pinionsfacinginward, with outward-extending squareshanks 21 and 22 integral thereof, said pinions and shanks being securedto the respective shafts 17 and 18, openings 23 and 24 being formed inthe disk 10 for them to rotate in, as shown in Fig. 5. Said pistons 15and 16 are also secured to the respective shafts 17 and 18 and arecarried thereby.

On each side of the abutments 3 and 4 are ports S and T, one-half ofeach being in each member A and B, whereby the pressure may be admittedor discharged from the cylinder formed by the surfaces C and D.

VThe disk 10 and the pistons 15 and 16 being assembled, as shown in Fig.5, they should now be brought to face the member B and .one end of theshaft 12 inserted on the opening R, by which the outer edge of the disk10 will rest on the surface 2, the inner portion resting on the surfaceF. The member A is now brought to face the member B and the disk 10. Theopposite end of the shaft 12 is theninserted in the opening Q, and thechimes a and b are brought into contact and are secured together bybolts passing throughthe corresponding holes ct and b, by which theopposite side of the disk 10 will be brought into contact with thesurfaces 1 and E.

By the above it will be apparent that the disk 10 will be revolublymounted in the casing and that the two concave oppositely-disposedsurfaces C and D will form a cylinder divided in the center by the disk10. When the pistons 15 or 16 are turned edgewise at right angles to thedisk 10, as in the position shown by the piston 16 in Fig. 5, thepistons will completely close the cylinder-space C and D, forming ahead.

Referring now to the auxiliary portions, 50 represents a Valve-seat(shown in section in Figs. 1 and 3) adapted to be secured to the outsideof the casing of the engine.

51 represents the valve-chest, mounted to the valve-seat, as shown.

52 represents a controlling or reversing slide-valve mounted in thevalve-chest and adapted to slide therein.

W represents an induction port leading into the interior of thevalve-chest, through which steam, water, or the like may be admittedinto the engine. Extending out from one side of the valve-seat 50 is anarm 53, in the end of which is pivoted a lever 54, provided with ahandle 55.

` rectly opposite to the piston 16.

56 representsabar secured to the valve 52,`

extending through a suitable aperture in the valve-chest, and the outerend is pivoted to the lower end of the lever 54, by which arrangement,it is apparent, the Valve 52 may through the valve-seat from the centerof the valve chest, and V represents the hollow space formed in the faceof the valve 52.

The engine being assembled, as above set forth, it will be seen thatshould steam, Wa-

ter, gas, or other motive force be admitted into the steam-chestlrthrough the inlet W, the lever 54 being perpendicular, as shown in thedrawings, it will be apparent that both ports S and T being closednopressure can be admitted into the casing or into the cylinder of theengine; but should the lever be drawn away fromthe engine to its fullextremity, then the valve r52 will be slid to the left, thus opening theport S into the space V and also opening the port T into the steam-spaceof the steam-chest, thus allowing the steam or other motive force topass up through the port T into the cylinder C D on both sides of thedisk 10, passing around through the cylinder, down through the port Sinto thel space V, and exhausting through the port U. It is alsoapparent that should the lever 54 be pushed toward the engine to itsfull extremity the port T will be brought into communication with vthespace V and` the port S will be brought into communica-` tion with `thesteam-space of the steam-chest, thus allowing the pressure to pass upthrough the port S into the cylinderon both sides of the disk 10,passing around throughthe cylinder, down through the port T into thespace V, and exhausting vthrough the port U. The disk 10 being placedinposition so that the piston 1G will closethe cylinder at a point justabove the channels LL' and I l', the piston 15 would be in the samepositionat a point di- Should pressure now be admitted from thesteam-chest 51 through the port S, it will be apparent that the pressureon the piston 16 would force it along in the cylinder. One of theshoulders of the shank 22, contacting with the surface 9, would preventthe piston 16 from revolving. When the piston 16 has moved a slightdistance, the gear-teeth 19 would engage the teeth'M, and thus give thepiston 15 a quarter-turn, carrying it parallel with the disk 10, (thescallop O allowing the shank 2l to turn at this poin) and thus carryingthe piston 15 between the abutments 3 and 4. As the pistons l5 and 16are turned parallel with the` disk their forward edges will come into;

contact with and rest on the "surface of the wing 5 or 6, depending onthe direction in` which the disk 10 is being revolved, and there` sil-edrate of speed. 4haust U and connect it to a supply of Water by be guidedbetween the abutments 3 and 4. After passing the Wing 6 the gear-teeth19 will engage the teeth N, thus `throwing the piston in position toreceive pressure, the

grooves L L and I I preventing it from re ceiving the pressure untilfully in position. At the same time the piston 16 has reached ltheopposite point in the cylinder, and as the pressure is taken by thepiston 15 the piston `16 has reached the grooves K K' and J'J,

thus relieving the pressure from the piston 16 in order that it may begiven a quarter- `turn, as above explained. By the above description itwill be apparent that pressure will be exerted circumferentially,causing rotation of the disk 10, and consequently ofthe shaft 12,carried thereby. The steam or air carried ahead of the pistons as theytravel in the cylinder and also all waste power issuing therefrom willbeexhausted through the port T into the space V and thenout through theexit U. By reversing the lever 54 to the opposite direction it will beseen that the port T will `become the induction-port and the port "SWill become the eduction-port, in which case the disk 10 will berevolved in the opposite direction from that above described.

Desiring to use my invention as a pump, I

have only to attach apulley (not shown) tothe outer end of the shaftl2,whereb'y the shaft 12 and the disk 10 may be revolved to the leftwith power from without the engine at the de I attach a pipe to theexand connect an exhaust hose or pipe to the inlet Wand theninove thehandle 55 toward the casing of the engine or pump. The waterwill then bedrawn in through the exhaust U, `car-- ried into the space V, up theport T, around `through the cylinder, down throughthe port S ginto thesteam-space in thechest 51, and discharged through the inlet W.

`ll/ly invention is perfectly adapted to accomplish theresults for whichit is intended,

and it is evident that changes in and modifications of the specificconstruction herein shown and described may be made and that analogousparts may be used to accomplish the same results Without departing fromthe spirit of my invention or'sacrilicing any of its many advantages,andA thespecic construction of the details of my mechanism in whichnovel features are embodied may be Varif ously changed without alteringthe essential principles which are'claimedV as new.

The terms upward, downward, right hand, left hand, and other similarterms are used only for convenience of description,

and it is .not intended by the use of such IOO do not dedicate any partofemy invention to the public and that I desireadequate and justprotection for every feature of my invention and the various partsherein shown and described that are new and useful and which involveinvention.
